Bill,  the Baxandal cct is great in lower voltage input applications,
but the one thing you don't want to do with HV sources is ADD voltage
stress.

It's got a special purpose transformer, the feed inductor and two
switching transistors. In theory you have to add a capacitor across the
transformer to create the resonant tank, but for the application I'm
talking about it may be difficult to wind the transformer with a low
enough parallel capacitance to get the sort of resonant frequency I'd
like to see.

That's not a lot of components.

 It doesn't matter how complex your circuits are, since they will never
be built.

You do like to think that. The last time that I went to the trouble and expense of getting something built, it let us find another low-level noise source which made it useless in the intended application.
I can afford that kind of minor extravagance, but I do try to avoid it.
